Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What bases should pair with the following strand? GGATT
A
GGATT
B
CCTAA
C
GCATA
D
TTACG
Explanation: 

Detailed explanation-1: -DNA base pair. Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA .

Detailed explanation-2: -The base pairs are adenine and thymine which forms a double bond and guanine and cytosine which forms a triple bond.

Detailed explanation-3: -We are given that the template strand of DNA has the base sequence CCTAGCT. Because cytosine will almost always pair with guanine and adenine with thymine, we can say that the complimentary sequence to this will be GGATCGA.

Detailed explanation-4: -A (Adenine) pairs with U (Uracil) instead of Thymine (T) and C (Cytosine) pairs with G (Guanine). Thus, the complementary RNA sequence will be: UAAGCUAC.
